Removable-type hard disk drive bi-directional ingress and egress structure

ABSTRACT

A removable-type hard disk drive bi-directional ingress and egress structure consisting of a connecting rod conjoined to the lower extent of a rotating shaft, with the other end conjoined to upper extent of another rotating shaft and thereby enabling opposite angles between the two upper and lower rotating shafts. When any single rotating shaft of the two upper and lower rotating shafts is selectively positioned by an extended handle, a tabular projection and two protruding catch hooks of a rotating shaft are utilized to coordinate the revolving of the rotating shafts by the handle such that the opposing action generated by the two upper and lower rotating shafts achieve a balanced ingress and egress effect at both the left and right sides. When the handle is pressed into closure, the catch hooks protrude due to the revolving of the rotating shafts and enables the drive housing to engage a replacement frame. When the handle is pulled open, since the rotating shafts and the connecting rod operate synchronously, the catch hooks are released from the check holes of the replacement frame, allowing flexible and efficient hard disk drive removal and installation under conditions of equalized force.

BACKGROUND OF THE INVENTION

1) Field of the Invention

The invention herein relates to a removable-type hard disk drivebi-directional directional ingress and egress structure, specifically akind having a two-sided synchronous ingress and egress replacement framethat enables efficient operation and, furthermore, an engagementstructure in which jamming is not easily induced.

2) Description of the Prior Art

Conventional hard disk drives are often engaged onto replacement framesby fixing their catch hooks to the sides of drive housings, as indicatedin FIG. 1, a conventional hard disk drive engagement structure. Aconventional hard disk drive 1 is equipped with projecting catch hooks11, with the said catch hooks 11 conjoined to the pull handle 12 at thefront extent of the hard disk drive 1 such that when the hard disk driveI is placed into the replacement frame, the said catch hooks 11 areengaged into the check holes of the replacement frame to achievemounting; when they are taken out, the pull handle 12 is tugged back toslant and thereby release the catch hooks 11 from the check holes tofacilitate the removal of the hard disk drive 1; since the catch hooks11 of such conventional structures are uni-directional engagement units(i.e., have a uni-directional force vector), this results in animbalance of force that not only results in inefficient operation, butalso produces less than ideal mechanical component jamming; since thisshortcoming has long afflicted and troubled manufacturers as well asconsumers, a removable-type hard disk drive bi-directional ingress andegress structure of increased practical value among such products istruly needed, which is the motivation of the invention herein.

SUMMARY OF THE INVENTION

Therefore, the primary objective of the invention herein is to provide aremovable-type hard disk drive bi-directional ingress and egressstructure consisting of a rotating shaft with a connecting rod at itslower extent, the opposite end of which is conjoined to the upper extentof another rotating shaft, enabling thereby an opposite angle betweenthe two upper and lower rotating shafts and, furthermore, when anysingle rotating shaft of the two upper and lower rotating shafts isselectively positioned by an extended handle, a tabular projection andtwo protruding catch hooks of a rotating shaft are utilized tocoordinate the revolving of the rotating shafts by the handle such thatthe opposing action generated by the two upper and lower rotating shaftsachieve a balanced ingress and egress effect at both the left and rightsides; when the handle is pressed into closure, the catch hooksrespectively engage the check holes of the replacement frame and whenthe handle is pulled open, since the rotating shafts and the connectingrod operate synchronously, the catch hooks are released from the checkholes of the replacement frame, allowing flexible and efficient harddisk drive removal and installation under conditions of equalized force.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring to FIG. 2 and FIG. 3, the isometric and exploded drawing ofthe present invention, the invention herein consists of a hard diskdrive drive housing 2 having sleeve slots 21 and 22 respectivelydisposed in the two sides of the front end such that a rotating shaft 23of a handle 24 is slipped in from the front of one end, wherein the saidrotating shaft 23 has a round recess 231 that provides for the placementof a spring 25, and extending from the periphery of the rotating shaft23 is a tabular projection 26 and formed in the said tabular projection26 is a catch hook 261 and a through-hole 262; after a mounting tie 27is inserted into the said through-hole 262 and fastened to a connectingrod 28, the other end of the said connecting rod 28 is coupled to athrough-hole 291 on the periphery of another rotating shaft 29 and,furthermore, the said rotating shaft 29 has disposed a catch hook 292similar to that of the rotating shaft 23, enabling the two ends of theconnecting rod 28 to be pivotably conjoined to the upper and lowerextent of the rotating shafts 29 and 23, respectively; furthermore, thecenters of the rotating shafts 29 and 23 enable the pivotableconjoinment of the two ends of the connecting rod 28 at opposite anglesrelative to the lateral aspect of the centers such that after the tworotating shafts 29 and 23 are respectively slipped into the sleeve slots21 and 22 of the drive housing 2, a mounting pin 100 is inserted intothe mounting holes 230 and 290 at the centers of the rotating shafts 29and 23 to mount them to the drive housing 2.

A step section 241 is disposed on the surface at the other end of thesaid rotating shaft 23 handle 24 and, furthermore, a tensile latchingcomponent 30 is situated at one side of the front opening of the saiddrive housing 2 such that when the handle 24 is pressed in, the latchcomponent 30 engages the handle 24 and the catch hooks 261 and 292protrude from the two sides of the drive housing 2 due to the revolvingof the rotating shafts 23 and 29, thereby providing for engagement inthe replacement frame 4 check holes 41, and when the latch component 30is pulled outward during removal and the handle 24 is pushed open due tothe elasticity of the spring 25, the catch hooks 261 and 292 of therotating shafts 23 and 29 then recede into the drive housing 2 as aresult of the revolving, enabling release from the replacement frame 4check holes 41 that facilitates hard disk drive removal such that thehard disk drive is smoothly placed in or taken out in an operation thatis flexible and, furthermore, with reduced mechanical component wearbecause the force against the two sides is equalized.

Referring to FIG. 4 and FIG. 6, the utilization and operationalembodiments of the present invention, when the handle 24 of theinvention herein is in a state of pressured closure, the drive housing 2latch component 30 engages the step section 241 of the handle 24 causingit to be secured and the catch hooks 261 and 292 protrude outward suchthat after the drive housing 2 is slid into the replacement frame 4,they are engaged in the check holes 41 and the drive housing 2 issecured onto the replacement frame 4.

Referring to FIG. 5 and FIG. 6, the utilization and operationalembodiments of the present invention, when the drive housing 2 isremoved, it is only necessary to the pull outward on the drive housing 2latch component 30, which releases the step section 241 of the handle 24and allows the handle 24 to open outward due to the tensile force of thespring 25, thereby causing the rotating shafts 23 and 29 to revolve acertain angle, resulting in the release of the catch hooks 261 and 292from the replacement frame 4 check holes 41 and enabling the efficientsliding out of the drive housing 2.

In summation of the foregoing section, since the invention herein hasthe catch hooks 261 and 292 of the rotating shafts 23 and 29 that arecoordinated with the handle 24 to enable hard disk drive ingress andegress into or from the replacement frame 4 in an operation that is evenmore efficient and flexible and, furthermore, the force is equalized toreduce to mechanical component jamming, the present invention is of apractical design which is an original innovation that is lawfullysubmitted to the Patent Bureau for review and the granting of thecommensurate patent rights.
